SIDE BEARING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented N ov. 6,y 1917.

Application led March 30, 1917'. Serial No. 158,492.

To all yiwf/0m t may concern.'

Be it known that I, JOHN F. OCONNOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Side Bearingsfor Railway-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invent-ion relates to improvements in side bearings for railway cars.

rIhe object of my invention is to provide a simple and efficient side bearing.

In the drawings forming a part of this specification, Figure 1 is a longitudinal section, partly in elevation, of a side bearing embodying my invention; Fig. 2 is a cross section thereof taken on line 2 2 of Fig. 1.

Referring to the drawings, the numeral 10 indicates my improved side bearing, coniprising a stancliion 11 adapted to be secured to a bolster, as, for instance, a body bolster 12. The stancliion comprises a base plate 13 and a pair of spaced apart members H lt, preferably integral therewith and at substantially right angles thereto, between which a roller 15 is mounted. The roller is adapted to engage a bearing plate 16 mounted upon the opposed bolster, as, for instance, the truck bolster 17. The roller 15 is of a general cylindrical shape, having a` longitudinal opening therein 18, the outer edge of which is concentric with the periphery of the roller, a longitudinal bead 2O being provided along the axis of the said cylinder and delining the inner edges of said longitudinal opening which is substantially semicircular in cross section. An arcuate key 21 passes through conformed openings 22-22 in the st-anchion and through the said opening 18 in the roller, the arc of said key being shorter than the are defining the outer face of said opening, the inner edge 19 of said arcuate key opposing the said axial bead 20 and the outer edge opposing the outer face of the said longitudinal opening 18. The said arcuate key is secured against accidental removal by suitable means, as, for instance, the cotter keys 23.

Upon movement of the bolster 12 and engagement of the bearing plate 16 against the roller 15, the arcuate key will act as a bearing for the axial bead or journal of the roller, and the roller will revolve until one of the edges 2:525 of the longitudinal opening therein, depending upon the direction of rotation of the roller, engages one of the edges 26 of the arcuate key. The space indicated at 27 in Fig. 1 of the drawings between the faces 25 and the faces 26, however, is sufciently great to permit all necessary movement of the roller in either direction. Upon separation of the two bolsters the roller, because of the greater weight of the portion 29 thereof forming a counterbalance, will `by gravity return to its normal position, being the position illustrated in the drawings.

I claim:

1. In a side bearing for railway cars, in combination: opposed bolsters; a stanchion secured to one of said bolsters; a roller mounted upon said stanchion; an arcuate key engaging said roller to the stanchion; the said roller having an arcuate opening therethrough to receive the key, the same being of greater width than the key.

2. In a side bearing for railway cars, a bolster, a stanchion mounted thereon, a roller associated with said stanchion, a key engaging said roller to the stanchion, the said key passing through an arcuate opening in the roller and forming a bearing for an axial journal with which the roller is provided.

3. In a side bearing for railway cars, a bolster, a stanchion secured thereto, a roller associated with said stanchion, an opposed bolster adapted to engage the roller, the roller having an arcuate opening therethrough, a key passing through said opening, a journal upon said roller extending into the opening and engaging the key.

4. In a side bearing for railway cars, a bolster, a stanchion secured thereto, a roller associated with said stanchion, an opposed holster adapted to engage the roller, the roller having an arcuate opening therethrough, a key passing through seid opening, u journal upon said roller extending into the opening and engaging the key, the roller having a oounteru'eght to revolve the sinne to normal position upon separation of the roller from its opposed bolster.

In Witness that I claim the foregoing I have hereunto subscribed my name this 20th l0 day of Mar., 1917.

JOHN F. OCONNOR.
